Immediate skin-to-skin contact right after birth is now backed by strong new evidence showing it helps newborns survive, grow, and develop better in both the short and long term.
Skin-to-skin contact means placing a naked or diaper-only newborn directly on a caregiver's bare chest, usually the mother, and covering both with a warm blanket. The baby's head is turned to the side so the airway stays clear, and the position is monitored by staff or family. This practice is also called kangaroo mother care (KMC), especially when used for preterm or low-birthweight babies and done for many hours each day.
Latest Guidelines and Why They Changed
In 2022, the World Health Organization (WHO) advised that preterm and small babies should start kangaroo mother care immediately after birth, without first being separated into an incubator.
This was a major shift from older guidance that called for 3–7 days of stabilization in a warmer before starting KMC. New data show that starting skin-to-skin right away saves more lives, reduces infections and hypothermia, and improves feeding in these vulnerable babies.
A 2025 updated Cochrane review also found such strong benefits of early skin-to-skin that the authors said it is no longer ethical to run trials where newborns do not receive it as part of standard care.
Major organizations like WHO, UNICEF, and the American Academy of Pediatrics now recommend beginning skin-to-skin within about 10 minutes of birth and keeping it for at least an hour whenever mother and baby are stable.
Early Life Benefits for Newborns
Skin-to-skin contact helps newborns adjust to life outside the womb in several key ways.
- It keeps babies warm by using the caregiver's body heat, lowering the risk of low temperature (hypothermia).
- It supports a more stable heart rate, breathing, and oxygen levels, which is especially important in preterm infants.
- It improves blood sugar control in the first hours and days, reducing episodes of low blood sugar.
- It lowers stress and crying, with studies showing reduced cortisol (a stress hormone) during and after skin-to-skin contact.
These early stabilizing effects are not just about comfort; they reduce complications, shorten hospital stays in some settings, and can improve overall survival, especially for babies who are born too early or too small.
Breastfeeding and Bonding
One of the clearest findings from recent research is that skin-to-skin contact boosts breastfeeding success, the Center for Breastfeeding said.
- The 2025 Cochrane review reported that about 75% of babies who had early skin-to-skin were exclusively breastfed at one month, compared with about 55% who did not.
- Mothers who do skin-to-skin in the first hour are more likely to keep exclusive breastfeeding for the first six months.
Skin-to-skin places the baby close to the breast, encourages natural rooting and sucking behaviors, and often leads to earlier first feeds. It also supports stronger emotional bonding and can increase milk volume when mothers express milk soon after a session.
For parents, this close contact tends to reduce anxiety and build confidence in caring for their newborn.
Brain and Long-Term Development
Beyond the first days, there is growing evidence that skin-to-skin care supports brain and behavioral development.
Randomized trials of preterm infants show that babies who receive kangaroo mother care have more mature brain activity patterns on EEG and better early neurobehavior scores as early as 7–14 days of life.
A 2025 systematic review and meta-analysis found that children who had KMC as newborns often show better cognitive and motor development in infancy and early childhood, especially when KMC starts in the first week and is done for many hours per day.
Long-term follow-up of one landmark trial into young adulthood has even reported higher IQ, better emotional regulation, and structural brain differences, such as larger volumes in key areas related to attention and control.
These findings suggest that the simple act of holding a newborn skin-to-skin can shape stress responses, sleep patterns, and neural connections in ways that support healthier development over many years.
How Often and How Long To Do It
For healthy full-term babies, many professional groups recommend immediate skin-to-skin for at least the first hour after birth, and longer if possible, including during the first breastfeed.
Parents can continue daily skin-to-skin at home during the first weeks and months, using it to calm the baby, support feeding, and strengthen their bond.
For preterm or low-birthweight infants, WHO advises continuous kangaroo mother care for as many hours per day as families can manage, ideally started right after birth. Research suggests that more frequent and longer sessions bring stronger benefits for growth, neurodevelopment, and emotional regulation, as per the Journal of Neonatal Surgery.
